Re-invent the wheel. Yes, we invented a new wheel again. Although, the original round wheel is already a classic design. Obviously, I would not like any other designer, just for a maverick look and the invention of a triangle or a square wheel. This time, in order to get rid of the constraints of the DAC chip, I used discrete components to form the R2R DAC module. This module not only looks "cool". Performance and functionality beyond any existing DAC chip.

 

Can support DSR's R2R DAC. Spring is the world's first R2R DAC to support DSD, and is by far the only one. This is not the DSD into PCM after the digital analog conversion, but directly to the discrete components of the DSD digital analog conversion

 

Spring has a variety of sampling modes and flexible conversion mode

NOS mode, without digital oversampling, the original data directly to the analog conversion. NOS can avoid these problems because digital oversampling can produce time-domain distortions such as ringing effects. NOS will usually have a significant impact on other performance indicators, but the spring design can make the NOS mode also maintain a good performance indicators.

OS mode, make PCM oversampling to reach a higher frequency PCM, the DSD oversampling to a higher frequency DSD, and then digital analog conversion.

OS PCM mode, whether it is PCM input or DSD input, will be oversampled to PCM mode for digital analog conversion

OS DSD mode, whether PCM input or DSD input, will be oversampled to DSD mode for digital analog conversion

Quan's digital input interface, including, USB (ground isolation), RCA, BNC, AES, optical fiber, HDMI interface, I2S. All digital input interfaces support DSD (DOP mode). Spring analog output interface for the single-ended and balanced each group.

 

Spring has an upgrade option, the machine's 4 filter capacitors replaced Jensen 4700uF / 63V. For the sound effects will be more relaxed, transparent

 

Spring is a R2R structure DAC, and is different from the modern popular delta-sigma-type DAC, R2R in a clock can be restored within a sampling point of the analog value, and delta-sigma is oversampled after the high-speed digital 0 and 1 to represent an analog quantity. In contrast, the conversion structure of R2R is directly and purely, and delta-sigma is essentially a digital chip, high-speed 0 and 1 to switch the digital signal to low-pass filter to the analog signal process is prone to various problems, Resulting in digital flavor, but also in the process of oversampling will inevitably lead to some ringing distortion. But the R2R structure of the DAC, because of the need for high-precision resistor network, the cost is very expensive. The delta-sigma DAC is essentially a digital chip, so the cost is very low.
